Unfortunately, this conflicts with the way mailman delivers stuff.  It
batches up posts to groups of people - typically five bunches.  This
means that deliveries aren't to any one individual recipient.  Using
these batches is bound to be quicker than making an individual send for
each person (particularly when the MTA implements smart batching to
sites, which mailman tries to support by grouping messages bound for the
same domain), so it's unlikely we'd want to defeat this feature for the
traceability - though there _are_ significant places where traceability
would be helpful...
